An airpot beverage dispenser having a body with a beverage cavity, a lid with lower and upper lid portions, a bellows within the upper lid portion, an actuator for compressing the bellows to increase the pressure of trapped air in the bellows, a duckbill valve, a skirt valve extending fully around the duckbill valve, and a spout. The skirt valve is movable into sealing engagement with a lid lower wall to define an air flow path from the bellows to the beverage cavity, and when the pressure of the trapped air in the bellows is sufficiently increased, the duckbill valve opens and passes the trapped air to the beverage cavity to force beverage out the spout. When the spout is moved to a stored position and the dispenser is in a locked state, the skirt valve serves as a relief valve to prevent over pressure in the beverage cavity.

A gas-filled resilient body and uses thereof are described. The gas-filled resilient body may be used as a valve member, as a spring or as a gas-propelled dispenser.

In exemplary embodiments of the present invention, “Flairosol” dispensing devices can be provided. Such devices utilize a combination of Flair® technology, pre-compression valves and aerosol-like pressurization of the dispensed liquid. Such a dispensing device has, for example, a main body comprising a pressure chamber, the latter being provided with a pressure piston and a pressure spring. The device further has a piston and a piston chamber which draws liquid from a container, for example, the inner container of a Flair® bottle, and fills the pressure chamber with that liquid as a user operates a trigger in various compression and release strokes. The piston chamber has both an inlet valve and an outlet valve, which serve to prevent backflow. Liquid exiting the piston chamber under pressure (supplied by, a user pumping the trigger) enters a central vertical channel which is in fluid communication with both the pressure chamber (above the pressure piston) and a dome valve provided near the outlet channel at the top of the dispensing head. The dome valve has a preset pressure, such that once exceeded by the liquid, opens and allows for a spray. If the liquid pressure drops below such preset pressure, the dome valve closes off the outlet channel, which serves to regulate the strength of the flow and preclude leakage. Alternatively, in an activated embodiment, for example, once the liquid is sufficiently pressurized, it can be dispensed by a user allowing the dome valve to open by pressing on an activation button that removes a dome lock.

A sprayer of liquids with trigger-operated pump includes a body which can be attached to the mouth of a container and a nozzle for delivery of the liquid. In the body is formed a pumping chamber in communication with the interior of the container and with the delivery nozzle. A one-way valve of suction and of delivery is located in the outlet duct of the liquid a system of precompression comprising a piston pushed with constant force by a spring in occlusion of the outlet duct such as to increase the pressure of the liquid in the outlet duct during the pumping, and also thereby increase the speed or the acceleration of the liquid in output from the nozzle.

A liquid dispensing system includes at least one container for storing the liquid to be dispensed, the at least one container having a neck defining a fill opening for the liquid. The system includes a liquid dispensing device releasably connectable to the at least one container, an exchangeable cartridge for an additive to be mixed with the stored liquid, where the cartridge is accommodated in the neck, and a piercing member for opening the cartridge. The cartridge includes a one-piece hollow body filled with the additive and with a pressurized gas, and the piercing member is arranged to pierce a wall of the hollow body. A method of dispensing a liquid by using the liquid dispensing system, and a cartridge for use in the liquid dispensing system and/or method.

Described is a cleaning system for personal hygiene comprising a bottle having an open neck, a spraying device, comprising a pumping unit, associated with said bottle at the open neck, a cleaning composition (C) inserted inside the bottle; the cleaning composition (C) comprises: (A) 1-20% by weight, preferably 1-15% by weight, more preferably 1.5-10% by weight, of a mixture of surfactants comprising at least one non-ionic surfactant and at least one amphoteric surfactant; (B) water up to 100% by weight, wherein the quantities of (A) and (B) are referred to the total weight of (A)+(B), and said pumping unit comprises a pump configured for dispensing between 1 cc and 2 cc of cleaning composition (C) for a stroke of said lever.

A trigger sprayer is made from a single grade of polymer capable of being reused as post consumer resin. The design allows for upright and inverted actuation. A pre-compression diaphragm ensures that dispensing stroke delivers a complete and uniform amount of fluid.

A pump for a vial intended to contain a cosmetic product includes a variable-volume dosing chamber defined at least partially by a deformable element. The pump operates by varying the volume of the chamber by elastic deformation of a membrane of the deformable element from an initial state wherein the chamber has a maximum volume to a deformed state wherein the volume of the chamber is minimal. The chamber is provided with a product inlet orifice and a product outlet orifice, and the pump includes deformation means of the membrane configured to exert pressure on the membrane. Finally, the pump includes means to purge the air from the chamber, that is activated when the membrane is in its deformed state, the purging means enabling the dosing chamber to communicate with the outside of the pump.
